Abstract: ABSTRACT OF THE DISCLOSURE    A transition metal carbonyl and a tertiary amine are employed as a homogeneous catalytic system in methanol or a less volatile solvent to react methanol with carbon monoxide and hydrogen gas producing ethanol and carbon dioxide.  The gas contains a high carbon monoxide to hydrogen ratio as is present in a typical gasifier product.   The reaction has potential for anhydrous ethanol production as carbon dioxide rather than water is produced.  The only other significant by product is methane.  Selected transi-tion metal carbonyls include those of iron, ruthenium and possibly manganese and osmium.  Selected amines include trimethylamine, N-Methylpyrrolidine, 24-diazabicyclooctane, dimethyneopentylamine and 2-pryidinol.

Abstract: PHD 80087                 14                      14.1.81 ABSTRACT: Amplifier arrangement.           The invention relates to an amplifier arrange-ment comprising at least one emitter-coupled transistor pair, the signal source being included in the emitter line. In accordance with the invention, the non-lineari-ties which occur are mainly caused by the second harmonic and this second harmonic is compensated for in that the base of at least one of the transistors of the pair re-ceives a compensation signal of suitable phase, which sig-nal is derived from the input signal or the output signal of the amplifier arrangement. This results in a multipli-cation process, which causes a second harmonic in the col-lector current of two transistors, which in the case of a suitable phase of the compensation signal at the input exactly compensates for the second harmonic caused by the non-linearity of the circuit. If the transistor pair is employed for gain control, especially for volume control, the direct voltage between the bases of the two transis-tors being varied, the compensation signal should also be varied.

Abstract: ABSTRACT OF THE DISCLOSURE           This  specification discloses  signal processing systems for converting a speech signal into a data signal for  controlling  a  hearing  prosthesis.  The  prosthesis includes an implanted electrode array which is adapted to stimulate   auditory   nerve   fibres   of   the  patient.          Stimulation occurs by application of electrical currents to  selected  electrodes  in  the  array.  The  processing system  generates  an  input  signal  corresponding  to  a received speech signal and a processing system estimates the amplitude and frequency of the fundamental voicing component of the speech signal  and also estimates the amplitude and frequency of at least one formant of the speech signal. The system includes programmable means for producing instruction data which causes application of electrical currents to selected groups of electrodes in the array to stimulate nerve fibers. The system includes use of programmable data which defines a predetermined relationship  between  each  group  of  electrodes  and  a selected range of at least one formant frequency and data defining  a  predetermined  relationship  between  another formant frequency and the delay between  stimulation of each  electrode  in  each  of  the  groups  based  on psychophysical   testing  of  the  patient.  The  system provides  selection  of  the  electrodes  based  on  the estimated frequency of the formant so as to produce the desired percepts in the patient. The programmable means within the system is further programmable to produce data which  determines  the  level  of  stimulation  of  each selected group of electrodes  and  determines  the  delay between stimulation of electrodes in each group dependent upon an estimated amplitude of the formants of the speech signal as well as on predetermined data relating to the sensitivity of each electrode implanted in the patient.

Abstract: ABSTRACT           A beam position processor (15) generates address signals representing the spatial coordinates of points on a simulated radar beam, for a plurality of beam directions.  The address signals serve for readout of weather information (e.g. cloud intensity, ceiling and base height data) from a data storage means (16) for further processing to form a video signal for display.          The storage means (16) is arranged for economy of memory capacity in that the higher order parts of the address are used to read out code words from a database memory (17).  Each code word selects one of a set of predetermined cloud patterns in cloud pattern memories (18, 19) and the lower order parts of the address access data corres-ponding to individual cells of the selected pattern.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to an improved valve pin bushing for use in a multi-cavity valve gated injection molding system and a method of manufacture.  Each valve pin bushing has a main body portion which is positioned between the end of a manifold plate arm and the heated nozzle, and a collar portion which projects from the main body portion with clearance beyond the end of the manifold plate arm.  The melt passage 34 extending through the manifold plate joins a melt duct extending diagonally through the main body portion and the valve pin is snugly received in a bore in the bushing.  The bore has an enlarged portion which receives the melt from the diagonal duct which then flows through the heated nozzle around the valve pin.  The valve pin bushing has a peripheral flange which laterally locates it in the cavity plate to offset frictional forces from thermal expansion of the manifold plate.  The valve pin bore is interrupted by a circumferential opening in the collar portion which vents corrosive gases through a vent duct in the main body portion.  The valve pin bushing is manufactured by first separately machining and drilling the main body and collar portions to form the circumferential opening vent duct, diagonal melt duct and bolt holes.  The collar portion is then brazed to the main body portion in a vacuum furnace to form an integral unit which is then centrally drilled to provide the valve pin bore.  In addition to improving lateral location, this structure provides the necessary length of snugly fitting bore around the valve pin to adequately seal against leakage of the pressurized melt during operation.
